[Abstract]:Image display is one of the important means for human to receive external information. The basic purpose of the display technology is to restore the object information in the original image, and bring the audience a real sense of the scene. From this point of view, it is inevitable that 3D display technology has become the mainstream of the display technology. The development of naked-eye 3D display technology is an inevitable trend in the future. In this paper, the UHD signal processing is studied, 4K2K is selected as the display resolution of the system, the signal transmission technology is introduced, the advantages of the V-by-One technology are analyzed, and the FRC and Up-scaler signal processing flow is designed for the system. The analysis and evaluation of the effect of UHD display are completed. Secondly, the technology of multi-view naked eye 3D display is studied. The depth extraction algorithm, DIBR algorithm and image mapping are introduced, and the effect test of multi-view naked eye 3D display is completed. Finally, the 2D/3D display switching technology is studied, the 3D display scheme based on parallax grating and microcylindrical lens is analyzed, and the 2D/3D display mode of this design system is tested. The main achievements and technical innovations of the thesis are as follows: (1) the system is a multi-view naked 3D display system, which supports 2D video processing operation of single view 2D video and dual view, and because of the use of 4K2K display screen, In multi-view naked eye 3 D display, high-definition resolution level can be guaranteed. (2) the system not only supports 4K2K source signal input and lossless display, but also supports Up-scaler to 4K2K display of non-4K2K video image signal, and also supports FRC operation of two kinds of signals. In addition, the system also adopts a new video transmission technology V-by-One; (3) the system supports the switching of 2D display mode and 3D display mode, which can achieve 4K2K ultra-high definition display in 2D mode, and naked eye 3D display with 9 views in 3D mode, and can switch different display modes under different application requirements; In addition, aiming at the concrete application of multi-view naked eye 3D system, a set of multi-view naked eye 3D TV solution based on highly integrated SoC TV processing chip, high performance FPGA chip and parallel and efficient FRC chip is designed. And complete the development of the corresponding hardware circuit and circuit module.
